dcblogs writes: The U.S. today (April 1) began accepting H-1B visa applications for the next fiscal year, with heavy demand expected. The visas will likely all be claimed by end of this week, and a major share of the H-1B visas will go to firms that use visa holders to displace U.S. workers. U.S. Citizenship and Immigration Services (USCIS) data is very clear about who are the largest users of H-1B visas: Offshore outsourcing firms.The IT services firms among the top 20 H-1B users accounted for a little more than 50% of the annual base visa cap of 65,000. This is for initial visas approved in the 2013 fiscal year, not renewals. "The offshore outsourcing firms are once again getting the majority of the visas," said Ron Hira, a public policy professor at the Rochester Institute of Technology in New York. "The program continues to promote the offshoring of high-wage American jobs."
